Composite microbial fertilizer capable of efficiently preventing diseases and insects and production method thereof

Abstract

The invention discloses a composite microbial fertilizer capable of efficiently preventing diseases and insects and a production method thereof. The composite microbial fertilizer is prepared by taking cassava bagasse and crop straws as main raw materials, adding a composite microbial fermentation preparation and carrying out semi-closed aerobic fermentation, wherein the composite microbial fermentation preparation comprises biocontrol bacillus licheniformis, paenibacillus polymyxa, bacillus subtilis and bacillus thuringiensis which are separately fermented and produced by a fermentation device; the fermented bacillus solutions are mixed, centrifuged and dried in vacuum to prepare the composite microbial fermentation preparation. According to the composite microbial fertilizer, the cassava bagasse and the crop straws are recycled; with combination with the composite microbial fermentation preparation, the cassava bagasse is recycled and reused, so that the technical content and the economic benefit of the composite microbial fertilizer are increased; the prevention and treatment effect on the diseases and insects of the crops is improved; secondary pollution of the cassava bagasse and the crop straws to the environment is avoided.

Description

technical field [0001] The invention belongs to the technical field of organic microbial fertilizer and its production, and in particular relates to a compound microbial fertilizer, in particular to a compound microbial fertilizer with high-efficiency disease and insect resistance functions and a production method thereof. Background technique [0002] my country's annual output of rice, wheat, corn, oil crops and other straws is as high as 500 million tons. Compared with chemical fertilizers and other energy sources, the economic value of straw is relatively low due to the huge quantity, scattered distribution, low density, large volume, high cost of collection, storage and transportation, and extremely inconvenient use. Therefore, at present, people mainly regard straw as waste and throw it away in the field, or directly burn it, which not only causes a great waste of organic resources, but also makes soil fertility decrease year by year, and its physical and chemical prop...

Problems solved by technology

These technologies generally have the disadvantages of low raw material utilization efficiency, long processing time, high total processing cost, unstable processing effect and product quality, etc.

[0003] Cassava alcohol residue is the waste after cassava alcohol processing. There are many disadvantages in the traditional fermentation and reuse of cassava alcohol residue: the fermentation time is long, generally takes about 15 days; the labor intensity is high, and it takes one person to stir a ton of cassava residue and mix materials during fermentation. Half a day; the active ingredients cannot be fully released and improved

Therefore, the disposal of waste residues in the production process of cassava alcohol has always been a headache for enterprises. If the cassava alcohol residues containing high nutrients are not handled properly, it will cause environmental pollution and waste of resources.

At present, there are few reports on domestic patented technologies for the production of compound microbial fertilizers by industrial microbial fermentation of cassava residues.
